SPECIFICATION forming part of Letters Patent No. 748,109, dated December 29, 1903.

' A Application filed November 11, 1901. Serial No. 81,890. (No model.)

T on whom it may concern:

Be it known that I, FIFE JOHN SCOTT, merchant, a subject of the King of England, re- 7 siding at 3 Oroham road, South Croydon, in the county of Surrey, England, have invented certain new and useful Improvements in- Strcet Cleansing or Scavengering Apparatus, (for which I have applied for patent in Great Britain, No. 12,498, dated June 19, 1901,) of which the following is a specification.

This invention has for its object to provide an apparatus or machine which shall effect the cleansing of public streets and other places with great economy and expedition; and the invention will be best understood by reference to the accompanying drawings, in.

Figure l is the right-hand part, and Fig. l the corresponding left-hand part, of a plan of the machine.

seen from the bottom of Figs. 1 and lfybut with certain parts omitted. Fig. 3is a ,sectional side elevation of part of the machine on the line 3 3 of Fig. I viewed from the bottom of that figure. Fig. 4 is an elevation of the left-hand side of part of the machine." Fig. 5 is atransverse vertical section on the line 8 8 of Fig. 2 looking toward the frontof the machine. Fig. 6 is a view similar to Fig. 5, showing the machine in its inoperative condition. Figs. 7and 8 are respectively an 010-, vation and a plan of the disk. Figs. 9 and 10 are elevations, taken at right angles to each other, of the rigid sliding frame; and Figs. 11

and 12 are elevations, taken at right angles to each other, of one of the two parallel guidebars, all these parts constituting. detached.

portions of a coupling embodied'in myimproved machine. Fig. 13 is a sectional side elevation, Fig. 14 a side elevation, and Fig.

15 a diagrammatic side elevation, showingby two steering-wheels; A A which latterare mounted in a vertically-pivoted under Fig. 2 is the righthand part, and Fig. 2 the corresponding left-hand part, of a side elevation of the machine as,

rotative connections. bly mounted on one end of a hollow shaft g,

carriage or yoke 0, provided with eyes or lugs c c, by means otwhich draft-animals or a steam or other road locomotive or the like may be attached toit- The hearings d d, in which the axle d. of the wheels A A is mounted, are, as shown in Figs. 5 and 6, situated one at the outside of the wheel A and the other at the inside of the wheel A and both of these wheels are free to rotate upon the said axle. To the wheel A are secured two parallel guide-bars e e, one of which is shown detached in Figs. 11 and 12 in front and end elevations, respectively, along which are free to slide guides ff, rigidly secured to two other guide-barsf'f',which are situated in planes perpendicular to those containing the guide-bars e e. The guides ff and guide-bars f f, as shown in front and side elevation, respectively, in Figs. 9 and 10, constitute a rigid frame which is capable of moving relatively to the wheel A only in a direction parallel with the guide-bars e e. G

tion of the above-named frame fff f on the guide-bars e 6.- By this arrangement it will be seen that it is possible for the disk G and road Wheel A to be adjusted in parallel planes, so as to be brought either concentric with each other or moved into different eccentric relationships without disturbing their The disk G is rotatawhich, as shown in Figs. 5 and 6, extends across the machine, with the road-wheel axle d passing longitudinally through it. This hollow shaft g has secured upon or formed in part with it a spur-wheel g which, in conjunction with a collar 9 prevents any axial motion of the disk Gon the said shaft, while leaving it free to rotate thereon.

Adjacent to disk G and rotatably mounted on the boss :thereof is a wheel or drum it, having teeth It in the same plane as the toothed wheel g opposite side of the machine (the two brackets H H being similar, excepting that H has no gear-wheels thereon) are formed with or constitute bearings or yokes wholly or partially encircling the hollow shaft g, and they are arranged so that they may be raised and lowered in guides 0. provided in or on the machine-frame A. Near the upper ends of the brackets H H are secured scre w-th readed nuts 2, which engage with the correspondingly-threaded lower ends of two vertical shafts t", on whose upper ends'are secured miter-wheels t geared together by other miter-wheels 2' and a transverse shaft t the latter of which is mounted in bearings i and at one end provided with a handwheel By rotating the hand-wheel 2' in one direction the brackets H H are raised, and with them the hollow shaft g, gearing h it it and disk G, the hollow shaft g thus being rendered eccentric in relation to the road-wheel axle d, although the disk Gt still retains its rotat-ive connection with the road-wheel A The wheel ord rum his provided with a springpressed sliding bolt 2' one end of which is adapted to engage with one of a series of holes or notches g in the disk G, the spring i tending always to effect such engagement. The bolt i is provided with an outwardlyprojecting end 6 which during the normal working of the machine performs no special function, but which when the wheel or drum h is raised, as before explained, is adapted to come into contact with a stationary cam or horn 71 as indicated in Fig. 6, whereby it is retracted (in opposition to the spring i .and its end is disengaged from the disk G,

which thereafter continues to rotate independently of the wheel or drum h. The cam or horn i is provided with a shoulder or abutment i Fig. 1, against which after the bolt 2' has been retracted, as last described, the bolt end i will rest to prevent the further rotation of the wheel or drum h and its directly-connected parts, this state of inoperation being maintained until by rotating the hand-wheel 2' in the required direction the bolt end 2' is loweredout of engagement with the cam or horn d at which juncture the spring i acts on the bolt 1' to force it into engagement with the hole or notch g next pre-- sented to it. On the hollow shaft g is suitably secured a cylindrical brush or refusedetacher J of any desired construction. This brush is of substantially the same external diameter as the road-wheels A A or preferably slightly larger, so that when it is coaxial with the said road-wheels its periphery will bear with the necessary pressure on the surface of the road. The brush or detacher J is almost entirely inclosed in a suitable housingj to as much as possible prevent the distribution or dissemination of the dust or particles removed from the road-surface, and at its back this housing is in open communication with a receptacle or pocket It, constituting the lower end of an elevator or conveyer K, by which the refuse deposited in said pocket by the brush J is conveyed into a wagon L, coupled to the rear of the brushmachine. The connected series of elevatorbuckets k is operated by a chain k and sprocket-wheels k of which latter the wheel 10 is in rigid connection with the before-described spur-wheel h The chain 70 is sufficiently slack to admit of the raising and lowering of the sprocket-wheel 70 independently of the wheel in.

The wagon L is of any desired construction. It is, however, advantageously provided with means whereb; the refuse discharged by the elevator K is satisfactorily distributed throughoutthesaid wagon. Forthispurpose, as shown in Figs. 1 and 2 the elevator discharges the refuse onto an endless apron Z, adapted to travel over two rollers l Zflthe shafts of which are jonrnaled in the sides of the wagon. example, the roller Z -rotary motion is transmitted by spur-and-sprocket gearing Z from one of the road-wheels L L. Depending from the hood or top L of the wagon are two or more deflectors Z Z whose lower edges are close to the upper surface of the apron Z and the vertical stems Z Z of which pass through slots Z Z in the hood L and at the outside of the latter the said stems are provided with clamping-nuts Z Z By these means the deflectors Z Z may be adjusted to and secured in any desired position or at any required angle. By these deflectors the refuse moved along with the upper reach of the apron Zis deflected sidewise and caused to fall over the edges of the said apron, and when the refuse becomes heaped up at the difierent parts of the wagon the deflectors Z Z are moved into other positions, so that the refuse may be delivered at other parts.

In advance of the brush or detacher J there are provided two scrapers B B, the stemsb b of which are supported in sockets b b and have fixed on their upper ends lever-arms 5 adapted to be moved over and secured by clampin -screws b b to quadrants b b By these means the scrapers B B may be adjusted to any desired angle or they may be rendered practically inoperative by being adjusted so as to be parallel with the direction of the travel of the machine.

The scrapers B B are each formed partly of india-rubber and partly of wood or metal and either in one piece,as represented in Figs. 1 and 2, or, as illustrated in Fig. 14, a plurality of pieces. When the scrapers are formed of a plurality of pieces, said pieces are connected to each other or to a common stock b Fig. 14:, in such manner as to enable them to yield independently of each other in passing over protuberances or obstacles on or into depressions in the road, or these pieces are arranged in advance of and overlapping each other. As an example the central section of the scraper (shown in Fig. 14) is represented in a raised position, such as it might assume To one of these rollers-say, for

I when passing over a protuberance on the roadsurface.

When the rotary brush-machine is at work, the brush or detacher J thereof is in its lower position and through the gearing h h h and g is rotated in the required direction at the necessary speed and removes the refuse from the road-surface and delivers it to the elevator K, which, as before explained, delivers itintothewagonL. When themachineistobe rendered inoperativeas, for example, when it is being returned from work-the brush or detacher J is elevated, so that it may be out of contact with the road-surface and at the same time be rendered non-rotative by the retraction of the spring-pressed bolt 11', as hereinbefore described.

In Fig. 2 I have indicated a seat M for the driver or operator; but this may or may not be provided, according to requirements.

If desired, scrapers J, as shown in Fig. 13, are interspersed among the fibers of the rotary brush or detacher J or alternate with brush-segments thereon,the term detacher being herein employed to include all of such possible variations.

Instead of the rotary-brush machine being propelled in the manner before described a steam or other motor N is, as shown in Fig. 15, secured upon the frame A and operatively connected with one of the road-Wheels A A In Fig. 15 the motor N is shown connected to the road-wheel A by chain-gearingn, and the steering-wheels A A are controlled by screw-gear n.

I wish it to be understood that the foregoing arrangements are merely given as convenient examples of means for carrying the invention into practice and that, if desired, other means may be employed without departing from the spirit of the said invention.
